Rane FVL 22 - Manual (Page 2)

FRONT PANEL DESCRIPTION
1. LOW CALIBRATION LED. The VCA’s in the FVL 22 attenuate the
most with the highest voltage across V1 and COMMON GND. Setting
the remote pot, ramp or switch to provide its highest voltage readies the
FVL 22 for calibration. During calibration, if this LED is on, adjust the
VOLTAGE CALIBRATION control clockwise, until the CAL indicator
comes on.
2. CAL LED. This LED illuminates when the maximum voltage is present
between V1 and COMMON GND and the calibration is just right.
3. HIGH CALIBRATION LED. During calibration, if this LED is on,
adjust VOLTAGE CALIBRATION counterclockwise, until the CAL
indicator comes on.
4. VOLTAGE CALIBRATION ADJUST. Use this screwdriver-adjust
control to set the VCA circuitry calibration when the external voltage at
V1 is set to its maximum level.
5. LIMIT THRESHOLD LED. When this LED illuminates, the preset
level threshold of the limiter has been exceeded.
6. LIMITER ADJUST. Rotate this screwdriver-adjust control to calibrate
the point at which the output limits. The inner ring of numbers show the
angle to rotate this control for balanced operation, the outer ring for
unbalanced output levels.
7. AUTO-SLAVE SWITCH. In the INDEPENDEDENT position, each
Limiter Channel operates separately. In the AUTO-SLAVE position,
both Channels attenuate the same amount when either one exceeds its
threshold.
8. POWER INDICATOR. Indicates the power on condition of the FVL 22.
